The magneto check is a crucial procedure in aviation to ensure that the engine’s ignition system is functioning correctly. During this check, the RPM (Revolutions Per Minute) of the engine is measured before and after deactivating one of the magnetos. The acceptable RPM drop varies depending on the aircraft type and manufacturer.
For most aircraft, an acceptable RPM drop is around 5% to 10%. However, it’s important to consult the specific aircraft’s maintenance manual for precise guidelines.
